Original application filed December 2,

To all whom it may concern Be it known that I, KARI. ENG-EL, a citizenof the United States, residing at Arlington, in the county of Middlesexand State of Massachusetts, have invented certain Improvements in Lasts,of which the following description, in connection with the accompanyingdrawings, is a Specification, like reference characters on the drawingsindicating like parts in the Several figures.

This invention relates to lasts and is herein set forth with especialreference to its application to the manufacture of welt shoes made inaccordance with the method described and claimed in my application Ser.No. 875,126, filed Dec. 2, 191 1, entitledMethods of making shoes, ofwhich this application is adivision, although it is not intended tolimit this invention thereby.

A principal feature of the invention is a last having a clenching plateoffset or separable. from its tread surface over an area extending overmore than half the length of the last. This structure'facilitates theinsertion of an insole member between the plate and the last bottom, aswill be explained. In the last shown the plate is offset from thelast-bottom over an area ex- I tending along the margin of thelast'bottom from about the heel breast to a point just back of the toetip.

Another feature of the invention is a last having a clenching platesecured to it at the heel end only, being separable from the treadsurface of the last at other points, in order to permit the insertion ofan insole member between theplate and the last bottom, for a purposewhich will be explained. Another feature of the invention is a lasthaving a clenching plate attached to the last only at the heel end andterminating short of the toe, and a supplementary clenching platesecured to the toe beyond the end of the former plate.

These and other features of the invention will be best understood fromthe following description of a preferred embodiment thereof, selectedfor purposes of illustration and 7 LAST.

shown in the accompanying drawings, in which Figure 1 is a perspectiveview of the last. Fig. 2 shows the insole used in practising the novelprocess referred to, and I Fig. 3 further illustrates the novel process.The last 12 has a lift 21 which may, if desired, be formed integrallywith its wooden portion, as shown. The clenching plate 13 is fastened tothis lift by the fastenings 16. The plate 13 is shaped like an ordinaryclenching plate used on a McKay last but is fastened to the last only atthe heel, as shown, and terminates short of the toe of the last. Asupplementary clenching plate 18 is fastened to the toe of the last bythe fastenings19. This plate is overlapped slightly by the plate 13. Thelift 21 separates the plate 13 from the last and permits the insertionof an insole member as will be described.

The use of the last in practising the novel welt shoe method of theparent application will now be briefly described.

The shoe upper 2 is cut substantially to its final outlines or to suchsize that the lower edge of the upper along the shank and at theforepart will terminate substan- I tially at the last edge, therebyeffecting an economy in cutting the upper leather. The toe and heelportions of this upper together with the toe and heel stiifeners arethen molded, preferably by the processes described respectively in myUnited States LettersPatentNo's 947,895 and 1,001,745, to the shapeswhich these parts assume in the finished shoe. In order, to providesuflicient material toenable the upper to be lasted over upon the insoleand also for securing it to the insole, a narrow strip of strong canvas3 may be attached to the lower edge of the molded upper through theshank and about the forepart; or a lining, if present, may be extendedbeyond, and fastened to, the edge of the upper. This canvas strip 3 isshown secured by stitches 5 to the inner face of the molded upper 2along its lower edge so that it projects a considerable distance beyondsaid edge and a welt 6 is also secured preferably by the same stitches 5along the lower edge of the molded upper 2 upon the outside thereof.

The insole to which the molded upper 2 is secured comprises preferably amain portion 8 of canvas or similar material to which the upper issecured, and a shorter flap 9' which may be of leather attached to themain portion at the toe end only thereof by cement or other suitablemeans and terminating approximately at the forward edge of the heelseat, although an insole of leather having a split extending from theforward edge of the heel seat toward the toe thereof and terminatingshort of the toe end, or an insole of other suitable material may alsobe employed.

The insole is placed upon the last with the flap 9 interposed betweenthe offset unattached portion of the plate 13 and the bottom face of thelast and with the main portion 8 coveringg-theentire bottom face of thelast. The prepared upper is then assembled on the last'and lasted overon to the insole 8 with the aid of the lasting strip 3 and the marginaledge of the upper at the heel, and the extension strip 3 is then securedin lasted position by tacks 20 driven into the insole. The tacks whichare driven to secure the upper to the insolev at the shank and forepartpass through the main portion 8 of the insole and are clenched thereonagainst the plate 13, and the tackssecuring the heel and extreme toeportions of the upper are clenchedon the inner surface of the compoundinsole. The succeeding operations upon the shoe including the attachmentof an outsole to the welt 6 are performed in the usual manner.

After the last 12 is withdrawn from the shoe, the flap orslip sole 9 iscemented to vthe main portion-8, thus covering the lasting tacks 20 inthe shank and forepart of the shoe. A heel seat filleris located in theshoe 7 'onthe interior of the shoe upon which the foot of the wearerbears.

a The advantages inherent the novel process described and inlthe shoeproduced by it are explained fully in iny'parent ap plication abovereferred to and need not be discussed in this application.

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is :5

7. A last having a. two-piece clenching plate, each piece being attachedonly at an extremity of the last in such manner that an insole membermay be placed between the plate and the last over substantially theentire shank and forepart portions} 8.
